Grok: how to get free trials and limited-time premium access

Grok, xAI’s conversational assistant, now offers multiple ways to access premium features without committing to a full subscription. Through free trials, temporary unlocks, developer incentives, and special promotions, users can explore Grok’s most advanced models, tools, and integrations before upgrading. Here we cover all available options, their benefits, and key conditions as of August-September 2025.

The free tier offers essential access with usage caps.

Grok’s always-free plan provides an easy way for anyone with an X account to test the platform and its basic AI capabilities:

• Models available: Grok Flash (lightweight model optimized for speed).

• Features included:

  • Text-based Q&A and short-form analysis.

  • Basic image understanding and small file summarization.

  • Document uploads up to 25 MB each.

• Usage limits:

  • 10 requests every 2 hours.

  • Limited image interpretation; video and audio analysis unavailable.

• Eligibility: Automatically active for all X users.

While the free plan supports casual use, users often reach request limits quickly, especially when working with larger files or multiple queries.

Grok Imagine promo unlocks image and video generation.

One of the most popular promotions, Grok Imagine, offers free access to AI image and video generation tools without requiring a paid subscription.

• Launch date: Mid-August 2025.

• Features unlocked:

  • Early Veo 3 integration for fast video demos.

• Usage caps:

  • Android users: Up to 25 renders/day.

  • iOS users: Limited to 20 renders/day.

• How to activate: Download the Grok Imagine app (Android rollout live; iOS gradually expanding).

This promotion targets creators, marketers, and developers seeking multimodal generation capabilities without upgrading to a paid plan.

Free weekend upgrades provide temporary premium features.

Since May 2025, Grok has offered limited-time “free weekend” feature drops that grant temporary access to premium tools and larger model contexts.

• Timing: Every Friday 00:00 UTC through Monday 08:00 UTC.

• Features unlocked:

  • Access to Grok 4 with extended reasoning capabilities.

  • Increased performance via priority API slots.

• Limits during promo weekends:

  • Up to 5× the usual request caps compared to the free tier.

  • Temporary unlocks do not carry over beyond Monday.

This ongoing event lets free users test advanced models and evaluate performance improvements before deciding on a paid upgrade.

SuperGrok 30-day trial unlocks Grok 4 Heavy.

For users considering full premium access, xAI introduced the SuperGrok free trial alongside the launch of Grok 4 Heavy in July 2025:

• Trial duration: 30 days of free access.

• Features included:

  • Grok 4 Heavy with a 256,000-token context window.

  • Up to 5 million tokens/month for research, analysis, and coding tasks.

• How to activate:

  • Visit Grok’s billing dashboard.

  • Click “Try 30 Days Free” on the SuperGrok plan.

• Important note: After the trial, the plan auto-renews at $300/month unless canceled before the 30th day.

This option is ideal for power users, analysts, and developers needing high-volume usage and extended context processing.

Free API credits for developers.

For developers and teams integrating Grok into custom applications, xAI offers recurring free API credits when opting into Grok’s telemetry program:

• Credits provided: $150/month in free API usage.

• Eligibility:

  • Requires at least $5 in paid API usage in the prior month.

  • Must opt-in to anonymous usage telemetry.

• Duration: Valid monthly while data sharing remains active.

• Applies to: Grok 3, Grok 4, Flash, and Heavy endpoints.

This is a cost-effective way for startups and researchers to prototype Grok-powered tools before committing to higher-volume enterprise plans.

Developer sandbox tokens for testing.

For new Grok developer accounts, xAI grants 20,000 free sandbox tokens to help users test the API without upfront payment.

• Value: Approximately $0.30 worth of tokens.

• Activation: Automatically applied upon new organization creation.

• Expiration: Tokens must be used within 14 days of account setup.

This small allowance is particularly useful for experimenting with Grok’s API structure, testing authentication flows, and validating integrations.

Student pilot program grants free Grok 4 access.

As of August 2025, xAI launched a student access pilot across selected U.S. universities, allowing students to test premium capabilities:

• Features included:

  • Grok 4 Standard with up to 800,000 tokens/month.

  • Core research, summarization, and coding features.

  • Requires a .edu email.

  • Registration through the university’s xAI partnership portal.
